I decided to explore the quality of Winsor & Newton Payne's Gray oil paint. It's transparent, according to the WN color chart, with blue undertones from the copper phthalocyanine pigment it's made from, along with carbon black. (Color index: PB29, PBk7, PB15)
I made a half tone by mixing 1/2 Payne's Gray and 1/2 Titanium White, then made a similar half tone from every color on my palette, then mixed the Payne's Gray half tone with each of my color palette half tones. The result; a series of muted, yet vibrant grayed colors, as you can see in the third and sixth rows of my color chart.
I imagine that muting these grayed colors with additional white will give me a series of grays that have many uses: sky colors, white fabric colors, shadow colors, etc.
I've added Payne's Gray to my palette in place of black. I think it will be a good addition!
But I still have one question, why did Winsor & Newton name it 'Payne's Gray?'
